asp.net 实现在线浏览word文档(word转html)

最近在做word文档在线浏览,找了种种方法、控件之后,回归到word转HTML,在线浏览....

一下是后台代码,前台html页面默认代码即可。


因为用文件如下:using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.IO; using Word = Microsoft.Office.Interop.Word;



using Word = Microsoft.Office.Interop.Word;没有引用好组件时,此处会报错,找不到Interop之类的,

这时需要在引用里面引用组件.net下的Microsoft.Office.Interop.Visio,Microsoft.Office.Interop.Word


后台代码如下:


protected void Page_Load(object sender, EventArgs e) { string relativePath = Request.QueryString["FilePath"]; //相对路径 ,从跳转页面得到文件相对路径。 if (relativePath == "" || relativePath==null) return; string serverPath = Server.MapPath(relativePath); //相对转服务器对应路径 string html = serverPath.Replace(".doc", ".html"); if (!File.Exists(@html)) //html页面不存在,把word转换成html { string filename = WordToHtml(serverPath); StreamReader fread = new StreamReader(filename, System.Text.Encoding.GetEncoding("gb2312")); string ss = fread.ReadToEnd(); Response.Write(ss); //直接写字符串到网页会发现,文字可显示,图片、表格无法显示。因此在后面重跳转到html文件页面。 fread.Close(); fread.Dispose(); } html = relativePath.Replace(".doc", ".html"); //html文件也存储在同样的路径下,站群软件, //只需要改了原路径的后缀即可得到html文件路径 Response.Redirect(html); return; } /// /// word转成html /// /// private string WordToHtml(object wordFileName) { //在此处放置用户代码以初始化页面 Word.Application word = new Word.Application(); Type wordType = word.GetType(); Word.Documents docs = word.Documents; //打开文件 Type docsType = docs.GetType(); Word.Document doc = (Word.Document)docsType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] { wordFileName, true, true }); //转换格式,另存为 Type docType = doc.GetType(); string wordSaveFileName = wordFileName.ToString(); string strSaveFileName = wordSaveFileName.Substring(0, wordSaveFileName.Length - 3) + "html"; object saveFileName = (object)strSaveFileName; docType.InvokeMember("SaveAs", System.Reflection.BindingFlags.InvokeMethod, null, doc, new object[] { saveFileName, Word.WdSaveFormat.wdFormatFilteredHTML }); docType.InvokeMember("Close", System.Reflection.BindingFlags.InvokeMethod, null, doc, null); //退出 Word wordType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod, null, word, null); return saveFileName.ToString(); }
